Winchester USA Rifle Ammunition

The Winchester USA 223 Rem FMJ 55gr is high-quality ammunition that suits a wide range of needs for high-volume rifle shooters. Incorporating a full metal jacket bullet, this ammunition offers positive functioning and no expansion for consistent accuracy for target and range shooting. Plus, the Winchester USA 223 Rem FMJ 55gr provides reduced barrel fouling meaning fewer cleanings.Please Note: While the 5.56x45mm will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington Chamber. This is military-grade ammunition. It may show discoloration which is caused by a process known as annealing. This is completely normal.
